Vibration Monitoring - Savings assessment

[Jimi68]

Hello everyone,

Our company is going to change condition monitoring subcontactor in the nearest future, as well as new, more complex and simply better agreement. The same time the company is obliged to show quite significant savings this budget year. I strongly believe that the new and better monitoring manner must be paid back, but I have no idea how to assess, very generally, an amout of money resulting from that as savings. Could anybody help me, just by pushing my thoughts in a correct way. I would be grateful for that.

Best Regards

A simnple calculation might be to estimate the costs of planned maintenance, based on failsafe operation, and compare that with the costs of condition based maintenance.

JIMI68:

Machinery condition analysis allows you to, most of the time, schedule maintenance and repair times. Rather than run equipemnt until it suddenly and catastrophically fails. Once started it should be continued at regular intervals. Properly done, you should be able to see the equipment degrade so that maintenance can be planned. If vibration analysis is used it works best on rotating machinery. Reciprocating machinery is harder to do, but there are people out there who say they can. The savings comes about by being able to schedule maintenance and perhaps replace only bearings and gaskets instead of the whole peice of equiupment because ti failed catastrophically.

Thank you rob768 for your reply. The whole issue is that we had by now vibration condition monitoring implemented in our company. It was quite useful and a few times con mon helped to indicate a root cause of a problem on the machinery. Up to now we collected data with our analysers and sent the data for the analysis to expert company. However recent organisation changes forced us to change the agreement into more complex. We have no more people who could collect data + everzthing will be done bz expert company (SKF). By the accasion we improved reaction times in emergencies, the scope of measurements is a little bit wider etc. Generally it is an improvement of reliability. The same time we must find a certain amount of money of savings in actual budget year. My quick idea was that improved reliability could be shown as savings. However taking into consideration that we had con mon nad we just change its quality I found it really difficult to assess the amount of savings. It seems to me that your answer could be applied to the situation that there was no con mon at all and some day we start to monitor the machines.

Milosz, glad to have jelped you.
I don't you know if you are still looking for a company to either perform the analaysis, or both the measurements and analysis, but perhaps we could be of help. We have also been involved in setting up a measurements program by telemetry (for more capital intensive plants, off-shore wind turnbines in particular), but I guess that this is only commercially interesting in a few specific applications.

By telemetry in this case I suppose you mean on-line monitoring, by network. Hmmm, that's an option for the future, to be achivable with time, due to high costs. But yes, with time we would like to go for it, as that would minimize reaction times and could help to find emergency shutdown reasons easier.

Telemetry itself is used in our company to monitor liquid levels, pressures in storage tanks at our customers.

Thak you for your assistance.

Best Regards
